The Rift

"The Rift Where worlds collide and time is but an afterthought, a near-endless struggle plays out time and again. *This area is end-game content in which you can acquire high-power Sicarius cards. *This area can be completed multiple times for additional rewards."

- In-Game Description

The Rift is a bonus region, released on February 11th, 2019 in the Act II world map. This region is a set of maps where you can get supreme-level cards (represented by a 1st and 2nd gen Sicarius) by "farming" materials (cores) with and  trades.

Rift regions
You need a very high amount of Mystic Tablet to get the supreme version. Each map will feature their own card at multiple rarity:
 * Regular 3★+
 * Regular 4★+
 * Regular 5★+
 * Supreme 5★+, which has the same stat and extra skill as a supreme, but lower auto-abilities.

Note: These cards are fast learners. The regular 5★+ could be referred as a fake version of the supreme, like an Ultimeh Cards. For example, regular Extreme Ifrit 5★+ has Taijutsu while supreme Extreme Ifrit X has Mantra.

You can get the different cards by unlocking & completing nodes that requires cores. You get cores by spending Mystic Tablets or completing the challenge area (more info below). In addition, you can unlock chests in each Rift map to get various rewards by trading keys (more info below). Cores & Keys are restricted to the area where you get them. s and s (from Extreme Ifrit) can't be used on Shiva's region for example.

Mystic Tablet area
3 set of 2 nodes which you unlock via. Those nodes will be the main source of core & keys. * the chest that gives 9 free keys is on the 1 tablet node (Beginner's Hunting Grounds) on Ifrit Map. It's present on the 3 tablet node (The Rift Hunting Grounds) on subsequent map. **A daily is available on the item shop that you can buy every day for 1000.

Chest Exchanges
Golden Chests These chests can only be exchanged with. can be obtained from ranking in top 1-2000 in Battle Towers, or through event rewards including in Ring of Braves Item Shop. These treasure boxes contains only cores that can be used in that region, and can be unlocked an unlimited number of times (as long as you have keys). 1 key = 100 cores, which equates to about 7.5.

Silver Chests These chests contains various rewards that can be exchanged for with the keys specific to that map.

The Brink: Challenge area
When you get the first card (3+), you unlock the Challenge Area. Similar to Chaos Vortex, this is a challenge area with No Rental card allowed. Be sure to complete it if you aim for the cards! 5700 cores is about 1/4 of the amount needed for the Rift Supreme card.

Colony: Core area (ship)
This is the area where you "trade" your cores to unlock nodes to get the supreme-like cards. Cores are actually not used upon unlocking nodes, that means you "only" need 20 000 cores to get the last reward. Note: 1st gen is first 6 Rifts: from Ifrit to Anima; 2nd gen is 6 Rifts: from Belias to Bahamut.
